Plate 2 Wet-rice Cultivation, Bali

The case study of the Bali Wet-rice Cultivation is a unique example of such ecology where man has maintained the beauty of the land along with its purposeful activities. The success of the Balinese rice-cultivation depends upon precise control of water. Cultivation begins with the flooding of the fields, which remains under water for most of the 105 days growing cycle. There are 20 thousands temples existing in small islands of Bali.
